Heavy (aeronautics)

The term heavy is used, with exceptions noted below, during all radio transmissions between air traffic control and any aircraft which has been assigned a maximum takeoff weight (MTOW) rating of 136 tonnes (300,000 lb) or more. Aircraft with a MTOW rating between 7 t and 136 t are considered medium and aircraft with a MTOW rating less than 7 t are considered light. In the US, the FAA uses a slightly different categorization. Aircraft capable of maximum takeoff weights more than 41,000 pounds (19,000 kg) and less than 300,000 pounds are considered large.

Such "heavy" aircraft over 136 t create wake turbulence from the wings. The term is mostly used around airports during take off and landing, incorporated into their call sign so as to warn other aircraft that they need extra distance to avoid this wake turbulence. All wide-body aircraft, except for the Airbus A300B1 (MTOW of 291,000 pounds (132,000 kg), only two built and retired in 1990) and the Airbus A380 and Antonov An-225 (which are classified in the even larger category of super), are thus classified as heavy. Certain variants of the narrow-bodied Boeing 707 and Douglas DC-8 also were considered "heavy" based on MTOW.

Team Fortress 2

Team Fortress 2 is a team-based first-person shooter multiplayer video game developed and published by Valve Corporation. It is the sequel to the 1996 mod Team Fortress for Quake and its 1999 remake. It was released as part of the video game compilation The Orange Box on October 10, 2007 for Windows and the Xbox 360. A PlayStation 3 version followed on December 11, 2007. On April 8, 2008, it was released as a standalone title for Windows. The game was updated to support OS X on June 10, 2010, and Linux on February 14, 2013. It is distributed online through Valve's download retailer Steam; retail distribution was handled by Electronic Arts.

In Team Fortress 2, players join one of two teams comprising nine character classes, battling in a variety of game modes including capture the flag and king of the hill. The development is led by John Cook and Robin Walker, creators of the original Team Fortress. Announced in 1998, the game once had more realistic, militaristic visuals and gameplay, but this changed over the protracted nine-year development. After Valve released no information for six years, Team Fortress 2 regularly featured in Wired News' annual vaporware list among other ignominies. The finished Team Fortress 2 has cartoon-like visuals influenced by the art of J. C. Leyendecker, Dean Cornwell and Norman Rockwell and is powered by Valve's Source engine.
